I'm watching a video in VLC (which uses hw accelerated video decoding), and
quite often the computer gets stuck/unresponsive when I use chrome at the same
time.

Software versions (all archlinux packages from the standard repository,
architecture is AMD64):

  - vlc 2.2.1-6 
  - libva 1.6.0-1
  - libva-intel-driver 1.6.0-1
  - chromium 44.0.2403.155-1
  - linux 4.1.4-1


VLC Log, where it says to use libva:

[00007f6e4e26db68] core decoder warning: early picture skipped
libva info: VA-API version 0.38.0
libva info: va_getDriverName() returns 0
libva info: Trying to open /usr/lib/dri/i965_drv_video.so
libva info: Found init function __vaDriverInit_0_38
libva info: va_openDriver() returns 0

<--- here, I kill VLC, everything goes back to normal

dmesg, where it tells me to file a bug:

Video that was playing on VLC at that time (probably relevant to know the
hardware decoder chosen):
  ffprobe:
    Stream #0:0(und): Video: h264 (Main) (avc1 / 0x31637661), yuv420p, 854x478
        [SAR 1:1 DAR 427:239], 760 kb/s, 29.97 fps, 29.97 tbr, 90k tbn, 59.94
tbc (default)
